NEW QUESTION 40
You implement FBF on router R1 so that traffic from subnet 172.25.0.0/24 uses ISP-A and traffic from subnet
172.25.1.0/24 uses ISP-B. You create forwarding instances for ISP-A and ISP-B. You also configure static default routes inside each instance. However, the static default routes remain inactive.
In this scenario, which action would complete the FBF implementation?

Configure an RIB group that includes the routing instances and inet.0.

Apply a firewall filter under the firewall, but not to any interface.

Increase the route preference of the static routes.

Change the instance type to virtual router.

NEW QUESTION 41
What are two characteristics of IS-IS? (Choose two.)

IS-IS is an interior gateway protocol.

IS-IS L1 routers route traffic between areas.

IS-IS routes use a default preference of 20.

IS-IS L1/L2 routers route traffic between areas.

NEW QUESTION 42
Which statement describes how a generated route determines its next hop?

It uses the next hop of the first contributing route.

It uses a static next hop configured under the aggregate route hierarchy.

It uses the next hop of the least-specific contributing route.

It uses the next hop of the primary contributing route.

NEW QUESTION 43
You are using OSPF to advertise the subnets that are used by the Denver and Dallas offices. The routers that are directly connected to the Dallas and Denver subnets are not advertising the connected subnets.
Referring to the exhibit, which two statements are correct? (Choose two.)

Create static routes on the switches using the local vMX router’s loopback interface for the next hop.

Configure and apply a routing policy that redistributes the Dallas and Denver subnets using Type
5 LSAs.

Configure and apply a routing policy that redistributes the connected Dallas and Denver subnets.

Enable the passive option on the OSPF interfaces that are connected to the Dallas and Denver subnets.

NEW QUESTION 44
When trying to commit the configuration shown in the exhibit, you receive an error.
What is the problem?

You have not set the interface family correctly.

You have omitted the interface-mode accesscommand.

You have omitted the interface-mode trunkcommand.

You have not configured an IP address to the interface.

NEW QUESTION 45
You have two OSPF routers that will not form an adjacency. You enter the show log trace- ospfcommand.
Referring to the exhibit, which statement is correct?

There is a mismatched subnet.

The wrong OSPF area has been configured.

The physical connection has been disconnected.

You are stuck in the ExStart state.

NEW QUESTION 46
You are asked to deploy nonstop active routing (NSR) on a dual-Routing Engine platform. In this scenario, what are two additional requirements for proper operation? (Choose two.)

All routing neighbors must support graceful restart extensions.

Both Routing Engines must run the same Junos OS version.

Graceful restart must be enabled on all neighbors.

GRES must be enabled.

NEW QUESTION 47
Which two statements are correct about generated routes? (Choose two.)

Generated routes require a contributing route.

Generated routes show a next hop in the routing table.

Generated routes appear in the routing table as static routes

Generated routes cannot be redistributed into dynamic routing protocols.

NEW QUESTION 48
Your router receives two BGP routes for the same prefix. One route is learned from an IBGP neighbor, and the other route is learned from an EBGP neighbor.
By default, which route will be selected as active in this scenario?

The route learned through IBGP.

The route learned with the highest next-hop IP address.

The route with the shortest AS-path.

The route learned from the neighbor with highest router ID.

NEW QUESTION 49
Which IS-IS PDU should be used by a router to list all LSPs that it believes should exist in the link-state database?

CSNP

PSNP

LSP

IIH

NEW QUESTION 50
Referring to the exhibit, which three statements are correct? (Choose three.)

The IP source guard is enabled.

Dynamic ARP inspection is enabled.

DHCP snooping is enabled.

NEW QUESTION 53
Which two statements about BGP facilitate the prevention of routing loops within an autonomous system? (Choose two.)

Routes learned from IBGP neighbors are only advertised to other IBGP neighbors.

Routes learned from IBGP neighbors are not readvertised to other IBGP neighbors.

IBGP sessions must be configured as a logical full mesh.

IBGP sessions must be configured as a physical full mesh.

NEW QUESTION 54

Which firewall filter term is correct in this scenario?

term block-ssh { from { source-address 192.168.10.0/24; service ssh; } then reject; }

term block-ssh { from { source-address 192.168.10.0/24; protocol tcp; destination-port 22; } then discard; }

term block-ssh { from { destination-address 192.168.10.0/24; protocol tcp; destination-port 22; } then discard; }

term block-ssh { from { source-address 192.168.10.0/24; protocol tcp; source-port 22; } then discard; }

NEW QUESTION 55
